I have tried it, and it is a very good program. You do need internet access on your phone however to use this program. It will send a sms trigger to tell your phone to check for email. The phone will then log onto the internet to access your email.

EDIT:

Well the only problem I had with it was a network issue with Sprint. Emails with attachments would not set off the trigger. I would only know of an email if another email was sent to set off the trigger. I contacted pusheffect's developers and they said it was a network problem. It probably is with Sprint's gateway or whatever because I had the same problem with flexmail and emails with attachments.

Yeah, this seems like a nice app. I've used Exchange activesync before but now that all the Exchange hosting services have jacked their prices up, this is a nice alternative.

There was an app very similar to this (basically just an SMS interceptor) for Palm OS that I used to use on my Treo 600 but I can't remember the name of it. The great thing about it was not only could it trigger an email sync, but you could have it lock your Treo as well. If your Treo was lost or stolen, just send a text to it with a predefined word (like "lock") in the subject line and it would lock it.

Not all are that bad. I use sherweb.com - they are $9/mo for an exchange 2007 account (was on wm6 so had html email, now not And 1and1 are only $7/mo. The nice thing about sherweb is I have one exchange account (mine for $9) and one pop account (for someone else who doesn't need exchange) for only $1/mo. I know that general email hosting gives a lot of pop accounts, but I've never seen them at a place also with exchange like this. Was a great alternative.

Mail2web does work, but if you want your own return address you have to pay. That is only $5/mo, but you still need your own hosting company to forward emails from (or mail forwarding at your registrar - your choice
